hi my name is Devin, i got my Monte Carlo SS about 2 years ago, its been a bumpy ride( the suspension is out ), and i need some help, its throwing a lot of EVAP codes, and when driving it has, shut off and locked the steering and breaks, and runs very rough, despite sending it to the shop this problem has persist, please help.

 

I'm new to the forum but I think this is posted in the wrong area. Any way. What codes is it throwing? Do you have a scan tool? Does everything shut off when the steering locks up?

 

well it was throwing a evap circuit code, i cleared it, but when running it does what i can only describe as hiccuping, and will rev down and up, then shut off

 

So no other codes? Did you fix anything before you cleared the codes? I'm thinking you should check your timing.

 

no other codes, although it is telling me to change the oil, which i did less than 1,000 miles ago, and sorry for posting this in the wrong area, i am also very new

 

Location. What have you tested / replaced?

 

I have replaced the throttle positioning sensor, I've had the evap solenoid replaced, and ive checked all the fuses. this is not the first time the evap was acting up, but i will have the timing checked.

 

What motor NA or Supercharged?

 

NA, 3.8Lt

 

And running. Pop your hood and wiggle both battery terminals and cables. See if the engine stumbles. Then post here https://montecarloforum.com/forum/mo...repair-help-8/ giving as much info as you can.( Makes it easier to diagnose with out seeing the car).
